The bioavailability and fractionation of Cu reflect its deliverability in soil. Little research has investigated Cu supply to crops in soil under long-term rotation and fertilisation on the Loess Plateau. A field experiment was conducted in randomized complete block design to determine the bioavailability and distribution of Cu fractions in a Heilu soil (Calcaric Regosol) after 18 years of rota...

one of the most important adverse environmental effects of herbicide application in production systems is possible damage to non-target plants, such as crops that are grown in rotation. nicosufuron+rimsulfuron (ultima) is a sulfonylurea herbicide that recently registered for use in maize fields in iran. its residues may be present more than a season in certain conditions. to measure nicosufuron...

The effect of 93 field crop and pasture cultivars on the end-of-season population densities of Pratylenchus thornei in soil was determined in the field in southeastern Australia. Wheat and barley cultivars had different effects on the population densities of P. thornei. Most commercial wheat cultivars that are grown in southeastern Australia were susceptible, while the barley cultivars were res...

Cereal crop wheat, Triticum sativum L., is an important food and feed that grown all over the world. There a complementary relationship between legumes cereals for nitrogen resources, it was found intercropped acquire higher amount of atmospheric in comparison to as individual crop. Furthermore, both wheat pulse intercropping give benefits terms minimizing pests diseases. Intercropping not only...

Cotton (Gossypium hirsutum L.) is an important fiber crop in Pakistan with significant economic importance. Transgenic, insect-resistant cotton (carrying a gene from Bacillus thuringiensis (Bt)) was inducted the cotton-based cropping systems of during 2002, and now sown >90% fields country. However, concerns are rising that Bt would decrease productivity winter crops (sown after cotton), lea...

Shatadal, P., Jayas, D.S., Hehn, J.L. and Bulley, N.R. 1995. Seed classification using machine vision. Can. Agric. Eng. 37:163-167. This paper reports the results of applying digital image analysis in conjunction with statistical pattern recognition to measure the size and shape features of various seed types and to classify them into the primary grain, small seed, and large seed categories. Th...

The fungal pathogen Sclerotinia sclerotiorum (Lib.) de Bary is worldwide in distribution and pathogenic to more than 400 plant species. This disease causes significant yield losses of various important crops including sunflower, canola, and soybean. Applying fungicides and crop rotation are currently the major methods of controlling this disease. However, fungicide chemicals are expensive, not ...

Wheat, shelled corn and rice are the most popular grown cereal grains and rapeseed (canola) is the most popular grown oilseed in the world. Thorough literature surveys reveal that a large number of publications contain EMC/ERH data for these grains and oilseed. From these publications, experimental data points are extracted, forming data sub-sets suitable for evaluating the isotherm equations. ...

Biotech crops have now been grown commercially on a substantial global scale since 1996. This paper examines the production effects of the technology and impacts on cereal and oilseed markets through the use of agricultural commodity models. It analyses the impacts on global production, consumption, trade and prices in the soybean, canola and corn sectors. The analysis suggests that world price...
